Hi,
Has anyone any tips or tricks for mitring CF tubes with holesaws?
What I’ve found so far is low feed speeds, high drill speed and rigid clamping are important.
Thanks

I cant really answer your question but I actually was watching this video just the other morning. Saw he was using a diamond coated hole saw. I dont know if youre using this type or a regular tooth type. But maybe this will be another idea.
Thanks, interesting video. Diamond saws might be worth a go. Using metal saws at the minute. I wonder what the forum thinks about using coolant - I’ve heard some reports that it’s best avoided.
For my project I’ve only had to cut one size of hole through some very thick solid laminate. I used a saw from these guys.
Super fast shipping and a very high quality bit designed for composites work.
Not sure if it’ll meet your criteria, but thought I might share.
Thanks for that. Yours looks like an interesting project, I’ll have to have a look in more detail.
Diamond tools will be your best friend for carbon. Once you get them you’ll throw away everything else.
Toothed holesaws work fine but diamond work a bit better and wont dull any time soon.
I have done alot of tube fitting to make frames for boat parts. One tool I bought specifically for this is an oscillating spindle sander. This is just used to sand hollow shapes at specific angles etc. I had to get my own sanding bobbins custom made and diamond coated. The bed of the machine is adjustable to any angle and I also added a fence to hold the tubes from moving sideways too.
Thanks all. I thought of a bobbin sander as I’ve had good success with sanding drums, but I hit a roadblock on the variable diameter spindles. I’ll probably go back to that later. So I’m using holesaws in the meantime. I’ll have a go with some diamond saws.
I am a convert to diamond saws. Amazing! Thanks everyone
